"No fuss, just sits & waits for me to do it & then opens his mouth like PacMan waiting for me to drop his treat into it!" hehehe love it! he's got his priorities right!
my tiny little oldie is not diabetic but is pretty much all blind now -the vet insisted it wouldn't bother her and he was right. as long as i remember not to leave stuff for her to bump into, and to have doors either all the way open or all the way closed (she'll crash head-on into a half open door every time).
and i grow her fringe to keep the sun out. bright glarey sun seems to upset her. if i couldn't grow her hair i guess one of those little doggie sun-visors would be the go.
she follows sound really well.
and scent is a big one. when i mop the floors -like an ant, she can smell where her regular paths are- she gets a bit lost but quickly makes a new path. the house is only small and she remembers her way around anyway but i think her 'paw path' is helpful.
not long ago i heard that dogs can be scent trained e.g. a few drops of lemon oil in a spray bottle of water, it doesn't have to be strong enough for you to smell it, and you can mark walking paths, food areas, beds and stairs with scent so the dog learns safe familiar spots. or even use different oils for different areas. don't know if it works but it sounded good at the time and reassuring for newly blind dogs.
